>I have an ActiveX object on my form that continually updates certain info on my form. It seems to work fine until I click a button on my form to send out a message and wait for a response. While I am in a do loop, it does not get any of the ActiveX events. It doesn't even buffer them. I found the AutoYield property. From what it says I would think that with _VFP.AutoYield = .t. it should let the ActiveX control fire its events, but it doesn't. The same code in VB seems to fire the ActiveX events, but I would like to not have to try to use the Database functions in VB if possible.

Bill,

When VFP is running code in the foreground it does not process windows messages until it finishes the code that is running. Your loop is preventing any of the windows messages from getting into VFP. You need a DOEVENTS command somewhere inside your loop to tell VFP to pause a moment and process the windows events.

You should be aware that a DOEVENTS can seriously slow down VFP because it has to process all windows events and all of its own events before the code can continue. Therefore, if your loop is doing more than just waiting for a response you may want to use a counter and only issue the DOEVENTS every x times through the loop.
